He is correct. Especially when you compare the amount earned in dollars per hour.
So we know that most people like doctors and scientists do not work “incidentally” or for parnasa alone–there are many more lucrative ways to earn money for less time invested.
Luckily, many people in our history have disagreed with Joseph’s sources–people who are Torah Jews (although Joseph and others of his ilk may disagree). Our history is full of famous physicians and astronomers, who did not learn “incidentally”. And there are many full-time professional scientists and academics who are shomer mitzvot, who are living testimony to the erroneous nature of Joseph’s opinions.
